Abstract (en)
[origin: WO9514812A1] A single tier drying section apparatus (10) is disclosed for drying a web of paper (W). The drying section (10) includes a first and a second dryer (12, 14) which are disposed in a single tier (16) for drying the web (W). A vacuum roll (18) is disposed closely adjacent to and between the first and second dryers (12, 14) for guiding the web (W) from the first to the second dryer (12, 14). The vacuum roll (18) includes a rotatable roll shell (22) having a first and a second end (24, 26). The shell (22) defines an outer surface (28) and an internal chamber (30) which extends between the first and the second end (24, 26) of the shell (22). The shell (22) defines a plurality of channels (32, 33, 34) with each channel extending from the chamber (30) to the outer surface (28) such that the chamber (30) is disposed in fluid communication with the outer surface (28). A vane mechanism (36) is disposed within the chamber (30) for evacuating the chamber (30). The arrangement is such that a flow of air (38) flows towards the chamber (30) through the plurality of channels (32, 33, 34) for drawing the web (W) into close conformity with the dryer felt (20) when the web (W) extends around the vacuum roll (18).
